'ro ALL wHoM IT MAY ooNonRN: y

- VBe it known that we, O. K. COLLINS and W. B. GROVER, of Woodbury, NewJersey, have invented an Improvement in Vapor-Burning Stoves; and we dohereby declare the following to be a full, clear, and exacg` descriptionof the same, reference being had to the accompanying drawing and to theletters of reference marked thereon.

Our invention consists of a. burner, which communicates witha. reservoircontaining naphtha, or other burning iluid, and is constructedsubstantially as described hereafter, so that the iluid which passes tothe burner shall be vaporized, and shall pass irom the burner in theform of gas, thc latter, on being ignited, producing a lame, whichcontinues to vaporize the iluid as it passes into the burner.

Our invention further consists of a gas-generating burner, incombination with certain pipes, acondenser,

and a valve, so'that wlfen the gas is generated too rapidly in theburner it will raise the valve and pass to the condenser, where it isreduced vto a iiuid state. p f

In order to enable others skilled in the art to make and use ourinvention, we will now proceed to describe its construction andoperation. On reference to the accompanying drawing, which forms a partof this speciiicationl Figure 1 is a sectional elevation of our improvedcoal-oil stove.

Figu're 2, a plan view.

Figure 3, a sectional plan on the line 1 2, iig. 1; and

Figure 4, a detached sectional view, drawn to an enlarged scale.

A is an oblong box or casing of iron, open below and closed at the top,with the exception of thev openings avand a for receiving culinaryutensils, the whole being supported on suitable legs, a a. Within thebox, A., and at or near the centre of the same, is secured a burner, B,consisting of a case enclosing a chamber, y, and having at its lower endan annular iiange, b, a short distance below which is a disk,.c, therebeing communications through a number of small holes, e, between thechamber, y, and the narrow space, x, between the ilange, b, and disk, c.A pipe, C, communicates with the lower portion, and a pipe, C', with theupper portion, of the chamber, y-,j and to the bottom, d, of the chamberis secured a' pipe, f, extending upwards and nearly to the top of thechamber, y, its upper end being closed by a valve, g, the spindle, j, ofwhich extends through the bottom of the burner. The pipe C communicateswith' an oil reservoir, D, situated above -the box, A, and with the pipeC communicate two pipes, E E', the latter having at its upper. end anordinary gas burner, `l. With the pipe E communicates a pipe, F, thelower end of which extends, in the form-of a coil, F', through a tank',G, and into a lower tank or reservoir, G. The pipe C has al valve, z',which is maintained in contact with its seat by u. spiral spring, o. Thepipes C' E are p1 ovided with'cocks, s and t, the fo'rmer interveningbetween the burner, B, and reservoir, D,`and the latter between the twoburners, B and l. Naphtha or other burning iluid is introduced into thereservoir D, from which it flows through the pipe C into the chamber y;the tank G is lled win water, and the valve g is raised, `after whichthe burner is heated by a pan of ignited alcohol, or in any othersuitable" manner. vAs the iluid in the chamber, y, is heated, a gas isgenerated, which passes down the pipe f, and through the openings e,into the narrow annular space z, from which it passes in theform of anannular flame, the latter maintaining the burner at such a heat as tovaporize the contents of the chambery. lThe amount of duid introducedyinto tho chamber y may be regulated by means of the cock s, and theextent ofthe flame by adjusting the valve g. Should there be anexcessive pressure of gas, in consequence of \its too rapid generationwithin the burner, the valve i will be elevated, and 'the superuous 'gaswill escape through the pipe C to the pipe F and coil F', where it willbe condensed, and will flow in u liquid form into'the tank G', fromwhich it may be again transferred to the reservoir D. If alight isrequired, the cock t is turned so as to permit the gas to flow to theburner l, where Ait is ignited. The ilame of-the burnerB may be at anytime extinguished by depressing the valve g-to its seat at the upper endof pipe f. i o

Without conning ourselves to' the precise construction and arrangementof parte herein described, we claim as our invention, and desire tosecure byLetters Patent-.

A1. The burner B, consisting of the chamber y, eommuniciting with anelevated reservoir, the ilangevb, and

disk c, with then-intervening annular space w, communieating withthe'rsnid chamber y, the whole beingja'rrunged substantially as 'and forthe purpose described.

2.- The cmbination of the above withthe pipe. f and valve g.

3. The gas-generting burner B, in combination with a. pipe F, watentankG, and vulve and pipes Cend El I' In testimony whereof we havev signedeurl names te this specicfatin, in thepresence of two aubscxfi-bngwitnesses.
